These test methods may also be applied to nonmetallic materials with structures having appearances similar to those of the metallic structures shown in the comparison charts. NOK 1 ,00 excl.
Characterization of grain size in specimens with duplex grain size distributions is described in Test Methods E Link to Active This link will always route to the current Active version of the standard. These test methods may also be applied to nonmetallic materials with structures having appearances similar to those of the metallic structures shown in the comparison charts.
Specimens with Non-equiaxed Grain Shapes. These charts were constructed to reflect the typical log-normal distribution of grain sizes that result when a plane is passed through a three-dimensional array of grains. The benefits of a subscription: Add to Alert PDF. Active view current version of standard. Equivalent inch-pound values, when listed, are in parentheses and may be approximate.
Utilization of semi-automatic digitizing tablets or automatic image analyzers to measure grain size is described in Test Methods E This will give you two copies e1121-2 the standard. Webprint Printed and bound.
These test methods apply chiefly to single phase grain structures but they can be applied to determine the average size of a particular type of grain structure in a multiphase or multiconstituent specimen. Already Subscribed to this document.

Application to Special Situations. Measurement of individual, very coarse grains in a fine grained matrix is described in Test Astmm E We have no amendments or corrections for this standard.
For determining the mean grain size, and the distribution of grain intercept lengths or grain areas, for polycrystalline metals and nonmetallic materials with equiaxed or deformed grain shapes, with uniform or duplex grain size distributions, and for single phase or multiphase grain structures, use the companion standard ASTM E The three s112-12 procedures for grain size estimation are: Historical Version s – view previous versions of standard Translated Version s: Leave a Reply Cancel reply Your email address will e1112-12 be published.
These test methods do not cover methods to characterize the nature of these distributions.
ASTM E – 12 Standard Test Methods for Determining Average Grain Size
These test methods do not cover methods to characterize the nature of these distributions. Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. Determination of spatial grain size, that is, measurement of the size of the three-dimensional grains in the xstm volume, is beyond the scope of these test methods. Partially recrystallized wrought alloys and lightly to moderately cold-worked material may be considered as consisting of non-equiaxed grains, if a grain size measurement is necessary.
The precision of the method is a function of the number of grains counted. The test methods may also be used for e1112-12 structures having appearances similar to those of the metallic structures shown in r112-12 comparison charts.
